Mailing bags advantage
High Tensile Film Structure
We use high-quality PE resin or multi-layer co-extrusion structures to achieve excellent tensile strength and superior elongation performance, effectively reducing transportation risks during shipping and handling.
Lightweight Optimization
While ensuring superior durability and structural integrity, we optimize film grammage to reduce material weight, helping lower shipping costs and improve container loading efficiency without compromising performance.
Superior Waterproof & Moisture Barrier
PE film inherently offers excellent waterproof and moisture-resistant properties, effectively protecting contents from rain exposure, humidity intrusion, and environmental damage during transit.
Enhanced Puncture Resistance
Through optimized material density and molecular structure engineering, our mailers provide enhanced protection against sharp objects, minimizing puncture damage and significantly reducing burst failure rates.
Secure Self-Seal Performance
We apply permanent hot melt adhesive or high-tack pressure-sensitive adhesive to ensure secure and tamper-evident sealing under various transportation conditions. Our adhesive system maintains strong bonding performance across both high and low temperature environments.
Structural Flexibility & Customization
We offer customizable structural options including bottom gusset designs, roll-fed configurations, and die-cut handle styles to meet different load-bearing requirements and to ensure compatibility with automated packaging systems.
